pH of Weak Acids and Weak Bases Est. Length: 2:00:00 Landon Herbert: Attempt 2 Page 1: 1 WH IN 2 Question 1 (1 point) Niacin (HC6H4NO2, Ka= 1.5 x 10-5) is a weak acid. Its dissolution in water is as follows: HC H₁ NO₂ (aq) + H₂O(1) C6H4NO₂ (aq) + H3O+ (aq) The answer should have 3 significant digits. The pH of 0.100 M niacin is Example: 3.18 You may use the ice table method, or the formula: pH of a weak acid = - A Question 2 (1 point) Trimethylamine (C3H₂N, Kb 6.5 x 10-5) behaves in water as follows: M = log(√Ka a concentration C3H₂N (aq) + H₂O(1) C3H, NH+ (aq) + OH(aq) . The answer should have three. The pH of 0.100 M trimethylamine is. significant digits. Example: 8.97 You may use the ice table method, or the formula: pH of a weak base N 14+ log(√Kb a concentration)
